Burping coolant on e63?
Thanks




If not, I recommend that you take you car to a independent MB shop, and have them bleed your system. Having air means that coolant can be blocked from circulating, thereby causing your car to overheat.

Is your oil cooler fan running at all. I replaced my oil coolant temp sensor, as my oil temperature was wacky. My oil cooler fan comes on at 99 Celsius, and we checked that fact.
We also reset the system. Before all this happened my oil temp was 81 Celsius, it stayed there like clock work, then all the sudden it started deviating from 81 - 91 and not staying consistent.
So we had to replaced the oil temp sensor and now it runs a constant 87 all day. So it might be a oil temp sensor, and it wasn't easy to replace or cheap.
As it resides next to the AC compressor, and not easy to get at.
